This MotoSport guide walks you through safely replacing and bleeding the brake fluid on a 2018 Can-Am Outlander 850 DPS (MMY: CAN_AM;OL850DPS;2018). Follow every step carefully, use DOT 4 brake fluid, and take necessary safety precautions. If your machine is equipped with ABS or an aftermarket braking system, consult a dealer or service manual before proceeding.

What you need

  • Fresh DOT 4 brake fluid (clean, unopened bottle)
  • Clear plastic tubing sized to bleed nipple
  • Catch bottle (marked for brake fluid)
  • Brake bleeder wrench or correct open-end wrench
  • Turkey baster or syringe (to remove old fluid from reservoir)
  • Clean lint-free rags and isopropyl alcohol for cleaning
  • Jack or ramps and stands to safely support the machine
  • Gloves and eye protection
  • Rubber caps or tape to keep dirt out of the reservoir while working

Prep & Safety

  • Work on a level surface with the engine off and key removed.
  • Wear gloves & eye protection. Brake fluid eats paint & plastics; protect painted surfaces and clean spills immediately with water.
  • Support the Outlander securely if you need to remove wheels. For basic bleeding you can often leave wheels on but ensure calipers are accessible.
  • Keep the brake fluid bottle capped until ready to use to avoid moisture contamination.

Overview of system on the 2018 Outlander 850

The Outlander 850 DPS uses a hydraulic brake master cylinder with front and rear circuits operated by the hand lever and foot brake. DPS refers to Dynamic Power Steering and does not change basic brake-bleeding procedure. Some model variants may have auxiliary plumbing or optional ABS systems; if you see ABS components, follow manufacturer ABS-service steps or consult MotoSport tech support.

Step-by-step: Replace & Bleed Brake Fluid

1. Remove old fluid from reservoir

  • Clean around the reservoir cap and remove it. Use a turkey baster or syringe to remove as much old fluid as possible without contaminating the reservoir.
  • Wipe the inside lip clean and refill with fresh DOT 4 to the recommended level but do not overfill.

2. Prepare bleed points

  • Locate bleed nipples on each caliper and on any remote bleeder fittings. For the Outlander 850 DPS, bleed front calipers left and right and the rear caliper. Consult your service notes for exact nipple locations if needed.
  • Fit clear tubing over the nipple and route into a catch bottle partially filled with fresh fluid to prevent air re-entry.

3. Basic two-person bleeding method

  • One person pumps the brake lever or pedal several times and holds pressure.
  • The second person opens the bleed nipple about 1/4 turn to allow fluid and air to escape until the flow is steady and air-free, then closes the nipple while pressure is held.
  • Repeat until you see only clear fluid with no bubbles. Keep reservoir topped between cycles to avoid sucking air into the system.
  • Work from the caliper farthest from the master cylinder to the nearest. Typical order: rear, right front, left front, but verify by visual inspection of plumbing on your unit.

4. One-person vacuum or pressure method (alternate)

  • Use a handheld vacuum pump on the bleed nipple or a pressure-bleeder on the reservoir following manufacturer instructions. These methods let one person complete the job cleanly while maintaining reservoir level.

5. Final checks

  • After bleeding each circuit, top the reservoir to the correct level and reinstall the cap securely.
  • Check for a firm, consistent pedal/lever feel. If the lever feels spongy, repeat bleeding until firm.
  • Inspect bleed nipples and hoses for leaks. Torque caliper hardware and bleed screws to factory values if you removed them for access.
  • Clean all spilled fluid with water and towel; brake fluid can damage paint and plastics.

Post-service inspection

  • Road-test at low speed in a safe area to confirm braking performance. Recheck fluid level and for leaks after the test ride.
  • Properly dispose of old brake fluid according to local hazardous-waste regulations.

Model-specific notes for the 2018 Can-Am Outlander 850 DPS

  • The DPS (Dynamic Power Steering) system does not affect brake hydraulics but be cautious routing tools when working near the steering pump and hoses.
  • The Outlander 850 uses DOT 4 as the recommended fluid; do not mix DOT 4 with DOT 5 (silicone) fluids.
  • If your unit has optional electronic features or ABS, additional bleeding steps or a dealer-level scan tool may be required to cycle valves and purge air pockets.
  • Brake hoses on older 2018 machines can show wear; inspect hoses and banjo fittings while performing the service and replace any components showing cracking, swelling, or corrosion.
  • Consider replacing bleeder screws if they are rounded, corroded, or hard to open. MotoSport stocks replacement bleeder screws and related hardware for this MMY.

Troubleshooting

  • Persistent sponginess after multiple bleeds could indicate air trapped in ABS modulator, a leaking component, or a failing master cylinder. Stop and consult a qualified technician.
  • If the brake lever sinks slowly under steady pressure, suspect an internal leak in the master cylinder or a caliper piston seal problem.

Follow these steps to maintain a safe, responsive brake system on your 2018 Can-Am Outlander 850 DPS. For replacement bleeder screws, hoses, or DOT 4 fluid, remember MotoSport has the parts you need to finish the job properly.
